The beating left him bloodied, bruised and bewildered about why he was attacked.

The woman, Laquisha Jones, 30, of Los Angeles, was charged with assault with a deadly weapon, according to the Los Angeles County Sheriff’s Department, and was held on $200,000 bail.

A witness, Misbel Borjas, told CNN and other news organizations that the attacker used a brick in the beating of the man, who was identified by the authorities as Rodolfo Rodriguez. Several men soon joined in the attack.

The beating occurred around 7:30 p.m. on July 4 in an area of unincorporated Los Angeles County, a statement from the sheriff’s department said. It’s known as Willowbrook and is about 15 miles south of downtown Los Angeles. Mr. Rodriguez, who was visiting the area, was hospitalized for several hours, and is now recovering with family, the statement said.

On July 5, Ms. Borjas posted a video on Facebook in which Mr. Rodriguez can be seen sitting on the ground next to a red-stained sidewalk, the right side of his face spilling blood. He later gave interviewson television as he lay in bed, his face still covered in cuts and bruises.

“I can’t walk anymore,” Mr. Rodriguez, who was visiting family in the area, told CNN in Spanish. “I’m in so much pain.”

Mr. Rodriguez said to CNN that the woman told a group of men nearby — the men who came over and began kicking him on the ground — that he had tried to take away her daughter.

“But that’s not true,” he said, according to CNN, adding that he had not bumped into a child. “In the years I have been alive, I have never offended anyone.”

Ms. Borjas told CNN she tried to help Mr. Rodriguez, but the woman threatened her, too. Ms. Borjas snapped a photo of the woman, who was with a young girl.

Erik Mendoza, Mr. Rodriguez’s grandson, told CNN that his grandfather sustained a broken jaw, broken cheekbones, two broken ribs and bruises on his face, back and abdomen. He said Mr. Rodriguez visits from Michoacán, Mexico, twice a year and walks through the neighborhood every day after lunch.
